Federal Aviation Administration June 5, 2013 – Federal Register Recent Federal Regulation Documents

Proposed Modification of Class E Airspace; Brigham City, UT
Document Number: 2013-13365
Type: Proposed Rule
Date: 2013-06-05
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify Class E airspace at Brigham City Airport, Brigham City, UT. The proposed decommissioning of the Brigham City Nondirectional Radio Beacon (NDB) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also would make an adjustment to the geographic coordinates of the airport.
Airworthiness Directives; Bell Helicopter Textron, Inc. Helicopters
Document Number: 2013-13302
Type: Proposed Rule
Date: 2013-06-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron, Inc. (Bell) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, and 407 helicopters with an Apical Industries, Inc. (Apical) emergency float kit installed under supplemental type certificate (STC) number SR01535LA. This proposed AD would require inspecting, labeling, and replacing the float inflation hoses. This proposed AD is prompted by an incident in which the floats installed on a helicopter failed to deploy. The proposed actions are intended to prevent failure of the emergency floatation gear to deploy during an emergency event.
Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters
Document Number: 2013-13300
Type: Proposed Rule
Date: 2013-06-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, EC155B1, AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters with certain EADS Sogerma pilot and co-pilot seats installed. This proposed AD would require inspecting the rear beam of each seat to determine if all of the weld beads are present and replacing the seat if any weld bead is missing. This proposed AD is prompted by a maintenance inspection that discovered a missing weld bead on the rear beam of a pilot seat. The proposed actions are intended to prevent failure of the pilot and co-pilot seats and subsequent injury to the pilot or co- pilot.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2013-13297
Type: Proposed Rule
Date: 2013-06-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This proposed AD would require inspecting the intermediate gearbox (IGB) fairing for a crack and inspecting the IGB fairing gutter (gutter), if installed, for a crack, separation, or interference. This proposed AD is prompted by reports of cracks, separation of the IGB fairing from the gutter and attachment supports, and subsequent interference with the tail rotor (TR) inclined drive shaft. The proposed actions are intended to detect a crack and prevent separation of the IGB fairing, which could result in interference with the TR inclined drive shaft and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. (Type Certificate Currently Held by AgustaWestland S.p.A.) Helicopters (Agusta)
Document Number: 2013-13293
Type: Proposed Rule
Date: 2013-06-05
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Agusta Model A109C, A109E, A109S, A109K2, and AW109SP helicopters. This proposed AD would require inspecting the lock wires securing the tail rotor (T/R) duplex bearing locking nut (locking nut) to determine whether any lock wires are missing or damaged. This proposed AD is prompted by reports of loosening T/R locking nuts, which if not corrected, could result in failure of the T/R and subsequent loss of control of the helicopter.
